Time zone comparison
Alaska Standard Time (AKST, UTC-08:00) vs Greenwich Mean Time (GMT, UTC+00:00). Right now AKST is 8h behind GMT. AKST is used in Anchorage while GMT covers United Kingdom (winter), West Africa, Iceland. Use the 24-hour grid below to find a meeting slot both sides will tolerate.
Heads up: these zones diverge on daylight saving.
AKST observes DST while GMT does not, so the gap shifts by an hour twice a year. In January the difference is 9h, in July it is 8h. If you are scheduling across the spring or autumn transitions, double-check the date.
Each row is one hour. Green rows are when both sides are inside 9 AM to 5 PM.

Alaska Standard Time (AKST) sits at UTC-08:00 today, while Greenwich Mean Time (GMT) is at UTC+00:00. The current gap is 8 hours, with AKST behind GMT. In practical terms, if your morning starts at 9 AM in Anchorage, your counterpart in United Kingdom (winter), West Africa, Iceland is seeing 17:00 on their own watch at that exact moment.
AKST is the working clock for Anchorage. GMT covers United Kingdom (winter), West Africa, Iceland. GMT and UTC agree to the second in practice. The UK uses GMT in winter and BST in summer. If your team is split between these two regions, the table above is the quickest way to spot the daily overlap window without doing the offset arithmetic in your head.
Daylight saving matters here. Alaska Standard Time shifts forward an hour on the second Sunday of March (US) or the last Sunday of March (Europe) and back on the first Sunday of November or last Sunday of October. Greenwich Mean Time stays on a fixed offset year-round. The IANA tzdata baked into this page handles every transition automatically, so the table reflects the correct wall-clock times for today's date. For dates further out, use the converter linked above and pick the target date explicitly.
Common scheduling traps are easy to avoid here. Pick a wall-clock time on one side, read the matching wall-clock on the other from the table, and write both into the calendar invite, never just the difference. If the meeting falls in the week of a DST changeover and one of these zones shifts, the absolute clock will drift by an hour from what the recipient expects. The table is computed for today's date, so for a future meeting open the converter linked above and pick the exact date.
One last note for asynchronous teams: business-hour overlap is the wrong metric for handoff workflows. If you operate on a follow-the-sun model, you actually want zero overlap, with one team logging off as the other starts. AKST and GMT differ by 8 hours, which is close to an ideal handoff window.
